PULLING-OVER MACHINE.

Specification of Letters Patent. Patented N 13, 191% Application filedApril 18, 1916. Serial No. 92,310.

To all whom it may concern Be it known that we, WILLIAM PHILIP MILLS andCHARLES h/IARTIN BAGSHAW, both subjects of the King of Great Britain,citizens of Leicester, in the county of Leicester, England, residing atLeicester, in the county of Leicester, England, have invented certainnew and useful Improvements in or Relating to Pulling-Over Machines, ofwhich the following is a specification This invention relates topulling-over machines employed in the manufacture of boots and shoes,and comprises an improvement therein intended more especially to enablesuch machines to be employed for pullingover work made on the turn-shoeprinciple, although it may in some cases be of use to facilitate thepulling-over operation on or dinary classes of work.

In turn-shoe work, as is well known, a marginal portion of the soleprojects beyond the edge of the last, and in carrying out thepulling-over operation care is necessary in ordervto avoid eitherbending the projecting edge or pulling the sole away from the last. Theprojecting marginal edge has presented a diflicnlty to the mechanicalpulling-over of turn-shoe work and one of the objects of the presentinvention is to overcome this and render possible the mechanicalpullingover of a turn-shoe without detriment to the marginal edge of thesole.

A further object of the invention is to provide, for use whenpulling-over ordinary work, means tosupport the edge of the insole andprevent it being pulled away from the last during the straining of theupper over the last. Such means are intended to be of service wheninsoles of soft material are used and where there is a tendency for theupper to displace the insole.

' For the aforesaid purposes the invention comprises a device or meansin the formof a support or rest adapted to occupy a posltion in contactwith the marginal face of the sole or insole and, during the upperstraining action caused by the movement of the last or pincers or both,to support or hold the said marginal portion of the sole or insoleagainst movement which otherwise might be imparted thereto by thefrictional contact of the upper therewith and such as would tend tocrush, bend or otherwise distort the marginal edge.

Conveniently the said device or means may take the form of a lipsituated in front of the pincer-jaws so as to engage the sole or insolein the region of the pull of the pincers upon the upper. The device ormeans may be associated with either the side pincers or toe pincers, orwith both side and toe pincers; In some cases it may be suflicient toemploy the device at the toe only, as for instance in turn-shoe workwhere the projection of the sole beyond the edge of the last is greaterat the toe than at the sides, but the number and disposition of thedevices employed will depend very largely upon the class of work beingoperated upon The support or rest may be mounted in such a manner as tobe capable of certain movements. For instance, itmay normally occupy anoperative position under, over or against the marginal face of the soleor insole according to the position of the work in the machine, tomaintain the edge of the said sole as aforesaid during the action of thepincers, after which when the pincers move inward to impart the indrawmotion to the upper, the said device may move away from the normalposition to allow the said operation of the pincers to take place. The

said movement of the device from the normal position may take place inone direction as for-instance it may simply move inward in front of thepincers; or on the other hand it may move in more than one direction asis necessary when the sole is cut or shouldered down around the marginas in turnshoe work, in which case the 11p or rest-normally engages thereduced part to support it and then may move away from the sole to clearthe shoulder before moving inward in front of the pincers.

The movement or movements of the supportinglip or rest may. andpreferably do, take place automatically with the movements of thepincersduring the indraw motion likewise the reverse movement or movements ofsaid device to return same to the normal position may, and preferablydo, take place automatically.

Alternatively however. manual means or a treadle or some equivalentmechanical ar,

. plates.

rangement may be employed to effect the change in position of thesupport or rest.

In further describing theinvention reference will be made to theaccompanying drawings, in which:

Figure 1 is a side elevation of a convenient form of the device of thisinvention applied to the wiper of a pulling-over machine pincermechanism.

Fig. 2 is a plan of the same.

Fig. 3 is a partly sectional elevation showing the device inassociationwith the work.

In the drawing, like parts are designated by the same reference.characters in all the figures.

i In the concrete form of the invention illustrated in the drawing, thesupport or rest 'is combined with the wiper of the pincer mechanism of apulling-over machineof the kind described in our application for U. S.Patent, Serial Number 7661, filed February 12th, 1915.

The said support consists of a lip or plate 1 attached to the forwardends of a pair of slides 2 situated one on each side of the wiper 3 andmovable to and fro within side plates 4 attached to the wiper byscrews'5.

The side plates at have longitudinal slots 6, and pins 7 on the slides 2extend through the said slots and have attached thereto correspondingends of a pair of tension springs 8. The opposite ends of the springsare attachedto pins 9 on the plates 41 said springs serving to normallydraw the slides 2 forward and hold the lip 1 a certain distance from theoperative end 10 of the wiper 3, which distance may be varied to suitrequirements by an adjustable slotted stop 11 attached to one of theslides 2 by a screw 12.

As shown in Figs. 2 and 3, the lip 1 is shaped to embrace the pincerjaws 13, thus enabling the upper edge 14, which comes under and servesto support the sole margin 15, to be brought closeup against-the back ofthe adjacent pincerjaw if neces sary.

Each slide 2 is supported in the side plate 4 by projections 16 and 17(Figs. 1 and 3) these being situated at opposite ends of the The loweredge 18 of each slide 2 which rests upon the projections 16, '17 isformed with an incline at 19 so that when the slides move backward inthe plates 4: and the incline 19 passes over the projection 16, thefront end of the slides and consequently the lip 1 carried bv same,will, for a purpose hereinafter described, fall as indicated by thebroken lines in Fig. 1. The slides 2 may fall by their own weight orunder the influence of a spring, and when the springs 8 return theslides 2 to the normal forward position after they have yielded, theinclines 19 ride over the projection 16 and raise the slides and lip. j7

\Vhen the device is used for turn shoe Work as shown in Fig. 3, itwillbe seen that normally the lip 1 engages the sole 20 underneath theprojecting marginal edge 15 thereof, so that when the pincer jaws 13close upon and draw down the upper 21 to stretch it over the last 22,the lip maintains the sole edge in place and prevents distortion orbending of the same which m ght otherwise be caused by the frictionalengagement of the upper therewith. 7

"After the pincers have descended and strained the upper over the lastand the pincer mechanism 23'commences to move inward, in the directionindicated by the arrow in Fig. 3, to wipethe upper 21 under the sole 20,the shoulderi'24 on the sole resists inward movement'of the lip 1 andconsequently causes the slides 2 to remain stationary relatively to theinwardly moving wiper 3 and supports 16 and 17 until the projections 16pass from under the inclines 19 whereuponthe slides move in. a directionat right angles to the sliding movement 2'. 6. they fall as shown bybroken lines in Fig. l, to bring the lip 1 below the shoulder 24. When,as just-described,thelip 1 passes out of contact with the shoulder 24the springs 8, which have been tensioned by the yielding of the slides,act to impel'Qthe slides forward again so that the lip '1- passes underthe sole 20 and thereafter moves inward in company with but in advanceof the pincers and wiper.

The device herein described mayalso be employed in the 1 mechanicalpulling-over operation in connection with ordinary work such forinstance as when insoles of soft or poor quality material are used, inwhich case the lip 1 normally situated under the edge of the insole willserve to support same and hold it against the bottom of the last whilethe pincers stretch'the upper, after,

,which the said lip will move inward under the insole during thewipingactionjof the pincer mechanism.

The hp 1 is preferably adjustable on the slides 2 for which purpose itis fulcrumed at 25 and has radial slots '26 through which the fasteningscrews 27 pass.

j The inventionis not to be limited to the concrete form of deviceherein described with reference to the accompanying draw-' scope of theinvention.

\Vhat we claim then is 1 1. In a P11111110 over machine, a pincermechanism .havmg a wiping in movement,

a gripper device therein, and a member carried by said mechanism toengage the margmal edge of the sole of the work and hold it against thelast, and resist the action of the gripper device during the operationof pulling the upper over the last, said memher, when the wiping-inoperation takes place, being arranged to move away from the operativeposition.

2. In a pulling-over machine, a pincer mechanism, a lip adapted toengage the marginal edge of the sole or insole of the work, slidesmovably mounted in the pincer mechanism and carrying said lip, andsprings to control the movement of said slides, for the purposedescribed.
